Abstract
In Section 1 we present the concept of a knot invariant of finite type and prove that all quantum group invariants are of finite type. Then we con-struct a universal knot invariant Z(K) of finite type, with values in a com-mutative algebra built on pairs of points on a circle. We also show that the quantum group invariants of XVII.3 can be recovered from Z(K) in a sim-ple combinatorial way. The proof of this fact, as well as the construction of Z(K), use the formalism of the KZ-equations and Drinfeld’s results stated in XIX.4.
